I've often imagined this life-giving scene as I inhale deeply, taking in the gift of life from the god Set. There are many scenes of the pharaoh being blessed by both Horus and Set, one example here:Set Gives Life to Horus

Recently I discovered a Middle Kingdom text in which the subject calls to Set, 'great of awe' to give him air:

From Coffin Text 407, Spell for the 7 knots of Mehet-Weret:

"O Seth who is in his peaking moment, great longhorned ox who is in
the middle of the northern sky,
Give me air in the middle of the wtnw-flood, the resting place of Mehet-Weret!
O you who are loud of voice,
and great of awe,
who sits in the middle of darkness,
give me air in the middle of the wtnw-flood,
the resting place of Mehet-Weret.
